Boosted Performance single turbo build

Boosted Performance

Like you said, torque is a result of tuning. A lot of tuners fee like the 400ft/tq is a really safe number on a VQ37, so it becomes the "norm" so to speak. We had 9psi of boost at about 3600rpm, so for sure the torque could be pushed way up...but why risk it.

I have customer with the DE making very close to 600ft/tq at 18-19psi, so the 62mm turbo is very capable. Perhaps a customer with a built motor will purchase this kit with the 67mm turbo, and push it hard....there may even be an insentive for somebody with an already built engine.

Sebz tuned my car, he told me not to push much more than 400 tq on the stock block...

Do you have any info on people pushing more safely?

I'm pushing 496 safely with my tune from Jon @ Z1. 5k miles boosted n she sees full boost EVERY time. I drive pretty hard, lot of street fun. As I said the DE motors were good to 429 before rods went. These motors r stronger so not sure why people seem to stop at the safe point of the old DE block. Christian also is running good torque. I think I even seen superchargers with the same amount of torque... I guess the crowd here is different.

I'll push the limit of the stock block when I get the kit

I wonder how the z stacks up against other big boys at these power levels

I received a package in the mail today and I just had to dust off my camera equipment to take some proper shots for my build thread.

Here's a sample,

I'm not sure if anyone knows, but I feel like the FI TDX midpipe connector with the 4 bolts is extremely similar, if not identical to the HKS Hi Power:



Kinda hard to see, but I wonder if they are the same? I'm looking into getting this kit later this year, and I was curious if I have to give up how nice my exhaust already is.

^^Sorry but that will not bolt up to the down pipe used with the F.I exhaust system. The two bolt flanges are inverse of what I see there....where the Y-pipe bolts up.

Hey Sasha, how big of a hassle would it be to change the flanges on the downpipes? As I will be installing Momentum headers for the 350z DE motor, I know the cat flanges would be different. Would this be able to be something you could custom make for me or would I just need to swap back to 370z HR headers?

Changing them on my end would not be a big deal. However, I am not sure how the DE headers fit on a VHR engine, and if the flanges sit in the same location at the same angle. I would assume they do, since the same turbo cast manifolds are used on both platforms.

I would be able to check the fitmen on my own 350z as well, since everything on that end should be the same geometrically.

I think the collector flange sits in a slightly different location, that's why Z1 had to make special test pipes to reach the exhaust... I could be totally wrong, but it doesn't make sense why they'd have to make special TP's for them otherwise.

Edit: I can attest to the fact that 350z DE longtubes do fit our cars on a case by case basis though. At least the flanges are in the right spots. (The primaries themselves may interfere with other components though, the particular set we tested fit fine however)

i installed the momentum headers today with DE OEM cats for the moment until my test pipes come in. everything lined up perfect with no need to modify a thing.the DE cats bolted straight up to my exhaust. the driver side header was a pain the *** to put in though so we had to loosen the motor mount to angle the motor to slide it in but the alignment is the same. i HIGHLY plan on ordering this kit in may so i will just need to request special flanges i guess. i feel like i always ask you on special requests lol. first to ask you about the oem oil cooler and now momentum headers lol. what else can i dig up?
